February 9, 2005 The Mercedes-Benz E 200 NGT switches from natural gas to petrol at the press of a button, does 227kmh and performs on par with the E200 KOMPRESSOR in either mode, and can halve running costs if run on natural gas alone. Throw in Mercedes exceptional retained value resale figures and the equation looks like a winner for when the right-hand drive models become available mid-year.
